Why it works: Asparagus and capers share more aroma than cooks usually use. They rank in the top 4% of all ingredient pairs, and cooks put them together in 75 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Asparagus with Melted Butter
Ingredients
Directions
Prepare
Trim the tough white ends from the asparagus and tie it in packages of about a dozen stalks each.
Prepare drawn butter according to the recipe for caper sauce, omitting the capers.
Cook and serve
Boil the asparagus in the boiling water with the salt for about 20 minutes until done.
Dip the toast briefly in the asparagus boiling water and place it at the bottom of the serving dish.
Arrange the asparagus in a ring on the toast with the heads in the center.
Serve the drawn butter in a gravy boat alongside the asparagus.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Forms the main vegetable; cooking softens its fibers until tender.
- Drawn butter
- Adds richness and a smooth, fatty moisture that complements the asparagus.
- Toast
- Absorbs moisture from the cooking water and serves as a base under the asparagus.
The step that matters
Boil the asparagus until done. Overcooking turns asparagus soft and dull in color, while undercooking leaves it fibrous and tough. Timing the boil to tenderness keeps the spears firm yet tender.
Swap the asparagus
How well each one fits the dish's main ingredients (butter, sauce, capers):
- Shallotfits better
- Mustardfits better
- Chivefits better
- Asparagusthe original
Fit is the average pairing score against butter, sauce, capers. Candidates are from the same food group and used in at least 100 recipes.
